Abstract: PROBLEM TO BE SOLVED: To shorten dial time by saving useless data display by comparing the area code of caller information received by a caller information receiving means and defining a number, except for the area code as a caller number when that area code matches the area code of the present station. SOLUTION: The off-hook operation of a hand set is monitored by a hook- detection circuit 4 and when off-hook is detected, a main control part 12 captures a telephone line by controlling a line interface 2. The main control part 12 monitors dial data coming from an operation input part 9, and when any dial data arrive, these data are judged. The main control part 12 judges whether or not the area code of telephone number of user is included in the caller information stored in a storage part 10. The main control part 12 sends caller data, excepting the area code of telephone number of user to a dial transmission circuit 5, and the dial transmission circuit 5 converts these data into dial pulses or DTMF signals and outputs them to a telephone line 1 later.

Abstract: PURPOSE:To make an appropriate light quantity of flash light attribute on exposure by computing the emission time of flash superposed on the accumulation time of a signal charge on an image pickup element based on distance information. CONSTITUTION:A means value BVc is found by photometric data inputted from a phtometry part 22, and shutter speed TV value is calculated from CCD sensitivity SVc and the diaphragm value AVc of an optical system.

And appropriate emission time Tf is calculated by comparing the AV value with the opening diaphragm value AV0 of the optical system. The emission timing Ttrg of the flash is found from the time Tf obtained in such a manner, exposure time TVc, and a time DELTAT until a state where a vertical transfer CCD can receive the signal charge is set, and the emission of the flash is permitted by setting FL.EL at H.

Title: Head for flattening device
Inventor: TOYODA HIDENORI
IPC: H05K3/34
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To enable flattening having a same height of solder bumps within a solder bump area even there is a substrate warp, by making a head as almost same size of the solder bump area formed on the substrate, and also by chamfering the outer peripheral part on a lower surface. SOLUTION: When flattening solder bumps 2, a head 5 heated at 130 deg.C is brought into contact under pressure with a solder bump area 3 with a load of 50 kg for 6 second. The height of the solder bumps 2 is accordingly pulled down to a height of 10 to 20 μm from a register and bumps are formed flat. A warp of a substrate 1 is merely 5 to 10 μm at a region of the head 5 size of which is made almost the same as an solder bump area 3 even in the case of the total warp of the substrate is 70 μm. The flatness ratio (smoothness) of the solder bumps 2 is controlled to a coplanarity of less than 30 μm. Further, the distance between the head 5 and the substrate 1 can be increased by a chamfer 6 being formed at an outer peripheral part of the head 5, therefore a risk of damage caused by the head 5 contacting with the substrate is eliminated.  In this way, the solder bumps 2 can be arranged in the same flat form.

Title: Excimer laser device
Inventor: ARIGA TATSUYA
IPC: H01S3/134
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain an excimer laser device which is further improved in exposure accuracy and optical processing accuracy by controlling halogen gas supply aiming at a partial halogen gas pressure that can minimize the output fluctuation of the laser device. SOLUTION: Laser pulse oscillation is performed in a laser chamber 2 by exciting a laser gas by discharge and the emitted pulsed light is narrowed in band by means of a band-narrowing unit 6. Then the pulsed light narrowed in band returns to the chamber 2 and is outputted as an oscillated laser beam L through a partially transmissive mirror 7 after the light is amplified in the chamber 2. Part of the outputted laser beam L is sampled through beam splitters 8 and 13 and made incident to a light receiving element 14. A CPU 15 detects the light energy Ei (i=1, 2, 3,...) of each pulse oscillation based on the received light output of the element 14 whenever the pulse oscillation is performed and controls a laser power source circuit 16 and a gas supplying device 17.  Therefore, a uniform pulsed light output can be obtained when halogen gas supply is controlled by giving the highest priority to the suppression of the fluctuation of each output energy.
